U.S., European heat waves 'virtually impossible' without climate change, study finds
Punishing heat waves have gripped America, Asia and Europe this July. A new study finds human-caused climate change is a major reason why.
The life-threatening heat waves that have baked U.S. cities and inflamed European wildfires in recent weeks would be "virtually impossible" without the influence of human-caused climate change, a team of international researchers said Tuesday. Global warming, they said, also made China's recent record-setting heat wave 50 times more likely.
Soaring temperatures are punishing the Northern Hemisphere this summer. In the U.S., high temperature records in the country's history.
